Simple way to shuffle an array

shuffleArray.js

/**
 * @param {Array} array 
 * @returns {Array}
 */
function shuffleArray(array) {
  let currentIndex: number = array.length;
  let randomIndex: number;

  while (currentIndex !== 0) {
    randomIndex = Math.floor(Math.random() * currentIndex);
    currentIndex--;

    [array[currentIndex], array[randomIndex]] = [
      array[randomIndex],
      array[currentIndex],
    ];
  }

  return array;
}
